  • In this paper, we propose a hybrid multi.system-on-chip (H-MSoC) architecture that provides a high-flexibility system in a rapid development time. The H-MSoC approach provides a flexible system-on-chip (SoC) architecture that is easy to configure for physical- and application-layer development. The physical- and application-layer aspects are dynamically designed and modified; hence, it is important to consider a design methodology that supports rapid SoC development. Physical layer development refers to intellectual property cores or other modular hardware (HW) development, while application layer development refers to user interface or application software (SW) development. H-MSoC is built from multi-SoC architectures in which each SoC is localized and specified based on its development focus, either physical or application (hybrid). Physical HW development SoC is referred to as physical-SoC (Phy-SoC) and application SW development SoC is referred to as application-SoC (App-SoC). Phy-SoC and App-SoC are connected to each other via Ethernet. Ethernet was chosen because of its flexibility, high speed, and easy configuration. For prototyping, we used a LEON3 SoC as the Phy-SoC and a ZYNQ-7000 SoC as the App-SoC. The proposed design was proven in real-time tests and achieved good performance.

  • Hairy roots of carrot were induced by Agrobacterium rhizogenes $A_4$ strain within about 2-4 weeks after inoculated from root disc. Early axonic culture is established in RCM agar medium and following is in MS rigid medium. After 15 days culture, the hairy roots were vigrous growth in about 10 times of initial inoculum. Anthocyanin contents of hairy roots were more than of ordinary roots. 2, 4-D ($10^{-4}mg/ l$), sucrose (5%), nitrogen source (0.03M) contained medium was optimized to growth of hairy root and contents of anthocyanin. Phenotypic alterations of leaves are observed in transformed plants and determined the transformation of hairy roots and the transformed plants by opine assay.
